Anyone running 4" silverline with muffler?

I wanna know whos running a 4" turbo back with muffler and cat-delete. How does it sound at idle compared to the factory one. Is it really loud under full throttle with windows up, how about when crusing down the road?

any info will be appreciated, thanks

I have the 4" mbrp kit. At an idle it sounds like a whooshing sound if you get right up to it. Not loud though. I can't hear mine at all on the highway. But when you stomp on it it gets pretty loud. It has a nice rumble under heavy acceleration though.

I have the silverline 4" with muffler and I would agree with the above poster for how mine sounds. More throaty at highway speed, but nothing annoying cruising.

I started with the muffler and removed it. The muffler does quiet it down a little bit.
